Description

Technical Field

[0001] This utility model relates to the field of pipeline repair equipment technology, and in particular to a rapid leak sealing device based on thermal pipelines. Background Technology

[0002] Rapid leak sealing for heat pipelines is suitable for emergency handling of leaks in various pipelines in heat transmission networks. It can quickly and effectively seal leak points under complex conditions such as high temperature and high pressure, ensuring the normal operation of the heat transmission system.

[0003] During long-term operation, heating pipelines are prone to leakage due to aging, corrosion, and external impacts. Once a heating pipeline leaks, it not only causes heat loss and reduces heating efficiency, but may also lead to safety accidents such as burns and fires, affecting the surrounding environment and personnel safety. Currently, the main methods for handling heating pipeline leaks are traditional welding, bonding, or pipeline replacement. Welding can only be carried out after the pipeline has stopped operating and cooled down, which is time-consuming and unsuitable for emergency leak situations, and high-temperature operations pose certain safety risks. Bonding methods are greatly affected by ambient temperature, humidity, and the leaking medium, and the bonding effect is unstable, making it difficult to guarantee long-term effective leak sealing on high-temperature and high-pressure heating pipelines. Replacing pipelines requires a lot of manpower, resources, and time, seriously affecting the continuity of heat supply.

[0004] To address the above issues, we have developed a rapid leak-sealing device based on thermal pipelines. Utility Model Content

[0005] This utility model discloses a rapid leak-sealing device based on a thermal pipeline, which aims to solve the technical problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rapid leak-sealing device based on a thermal pipeline includes a leak-sealing connector. A sealing baffle is fixedly connected inside the leak-sealing connector. A connecting rod is provided on one side of the inside of the leak-sealing connector. A conical plug is fixedly connected to one end of the connecting rod, which cooperates with the sealing baffle. The end of the connecting rod away from the plug extends to the outside of the leak-sealing connector and is fixedly connected to a roller. A spring is fixedly connected between one side of the inner wall of the leak-sealing connector and one side of the plug, located outside the connecting rod. An L-shaped frame is fixedly connected to one side of the leak-sealing connector. A cylinder is fixedly connected to the bottom of the L-shaped frame. The output end of the cylinder extends into the interior of the L-shaped frame and is fixedly connected to a pressure block, which contacts and cooperates with the outside of the roller. A flow monitoring sensor is fixedly connected to one side of the plug.

[0008] When the thermal pipeline is operating normally, the spring separates the plug from the sealing baffle, allowing the medium inside the pipeline to flow normally. When the flow monitoring sensor detects a leak that causes abnormal flow, the remote monitoring and control module activates the cylinder. The cylinder pushes the pressure block to squeeze the roller, which in turn moves the connecting rod and the plug, causing the plug to fit against the sealing baffle and quickly stop the leak.

[0009] In a preferred embodiment, an input pipe is fixedly connected to one side of the leak-sealing connector, and an output pipe is fixedly connected to the top of the leak-sealing connector. Both the input pipe and the output pipe are connected to external thermal pipelines via flanges.

[0010] When installing the leak-sealing device, connect and fix the inlet and outlet pipes to the corresponding interfaces of the heating pipeline using flanges, ensuring a tight connection so that the leak-sealing device can be connected to the heating pipeline system for timely handling of pipeline leaks.

[0011] In a preferred embodiment, the leak-sealing connector is made of ceramic fiber material, which has high temperature resistance and heat insulation properties.

[0012] In high-temperature thermal pipeline environments, leak-sealing connectors made of ceramic fiber materials can withstand the effects of high-temperature media inside the pipeline, while their thermal insulation properties can prevent accidental burns from external personnel, ensuring stable operation of the equipment and personnel safety.

[0013] In a preferred embodiment, the leak-sealing connector is internally fixedly connected to a waterproof sliding sleeve, and the connecting rod is slidably connected to the waterproof sliding sleeve.

[0014] During the operation of the leak-sealing device, the waterproof sliding sleeve prevents the medium in the pipeline from leaking to the connection between the connecting rod and the leak-sealing connector, ensuring that the connecting rod can slide smoothly in the waterproof sliding sleeve, so that the movement of the plug block is not affected and the reliability of the leak-sealing function is maintained.

[0015] In a preferred embodiment, a limiting strip is fixedly connected to one side of the inner wall of the L-shaped frame, and the pressing block is slidably connected to the limiting strip.

[0016] When the cylinder pushes the pressure block to move, the limiting strip plays a limiting and guiding role on the pressure block, ensuring that the pressure block moves smoothly in the correct direction and accurately squeezes the roller, so that the plug accurately fits with the sealing baffle to seal the leak.

[0017] In a preferred embodiment, a remote monitoring and control module is fixedly connected to one side of the L-shaped frame, and both the cylinder and the flow monitoring sensor are electrically connected to the remote monitoring and control module.

[0018] Staff at the monitoring center can view the flow data of the thermal pipeline in real time from the flow monitoring sensor through the remote monitoring and control module. When a leak occurs, the remote monitoring and control module automatically controls the cylinder to plug the leak. It can also be manually operated by staff remotely to achieve intelligent remote management.

[0019] In a preferred embodiment, the plug is made of high-temperature resistant silicone material, which can completely fit the sealing baffle.

[0020] When leak sealing is required, the high-temperature resistant silicone plug, under the action of the cylinder, tightly fits the sealing baffle. Utilizing the flexibility and sealing properties of silicone, it effectively seals the leak point. At the same time, its high-temperature resistance allows it to maintain good sealing performance even in the high-temperature environment of thermal pipelines.

[0021] The rapid leak-sealing device based on a thermal pipeline provided by this utility model has the following advantages:

[0022] In this utility model:

[0023] 1. The device has a simple structure and is easy to operate. It does not require complicated tools or professional skills and can seal the heat pipes in a short time, greatly shortening the sealing time and reducing heat loss and the scope of accident impact.

[0024] 2. The elastic sealing component uses high-temperature resistant rubber and springs, which can fit tightly and maintain good sealing performance even under high temperature and high pressure environments, effectively preventing leakage and greatly improving the quality of operation and efficiency of use compared with traditional devices.

A connecting rod 3 is provided on one side inside the leak-sealing connector 1. A conical block 4 is fixedly connected to one end of the connecting rod 3.

The pressing block 9 contacts and works in conjunction with the outside of the roller 5. A flow monitoring sensor 12 is fixedly connected to one side of the block 4.

[0033] In this embodiment: When the thermal pipeline is running normally, the spring 6 separates the plug 4 from the sealing baffle 2, and the medium in the pipeline flows normally. When the flow monitoring sensor 12 detects a leak that causes abnormal flow, the remote monitoring and control module 14 starts the cylinder 8. The cylinder 8 pushes the pressure block 9 to squeeze the roller 5, which drives the connecting rod 3 and the plug 4 to move. The plug 4 fits against the sealing baffle 2 to achieve rapid leak sealing.

[0034] In a preferred embodiment, an input pipe 10 is fixedly connected to one side of the leak-sealing connector 1, and an output pipe 11 is fixedly connected to the top of the leak-sealing connector 1. Both the input pipe 10 and the output pipe 11 are connected to external thermal pipelines through flanges.

[0035] In this embodiment, when installing the leak-sealing device, the input pipe 10 and the output pipe 11 are respectively connected and fixed to the corresponding interfaces of the heat pipe through flanges to ensure a tight connection, so that the leak-sealing device can be connected to the heat pipe system for timely handling of pipe leaks.

[0036] In a preferred embodiment, the leak-sealing connector 1 is made of ceramic fiber material, which has high temperature resistance and heat insulation properties.

[0037] In this embodiment, the leak-sealing connector 1 made of ceramic fiber material is used in a high-temperature thermal pipeline environment. It can withstand the influence of high-temperature medium in the pipeline, and its heat insulation performance can prevent accidental burns to external personnel, ensuring stable operation of the device and personnel safety.

[0038] In a preferred embodiment, a waterproof sleeve 15 is fixedly connected inside the leak-sealing connector 1, and the connecting rod 3 is slidably connected to the waterproof sleeve 15.

[0039] In this embodiment, during the operation of the leak-sealing device, the waterproof sliding sleeve 15 prevents the medium in the pipeline from leaking to the connection between the connecting rod 3 and the leak-sealing connector 1, ensuring that the connecting rod 3 can slide smoothly within the waterproof sliding sleeve 15, so that the movement of the plug 4 is not affected and the reliability of the leak-sealing function is maintained.

[0040] In a preferred embodiment, a limiting strip 13 is fixedly connected to one side of the inner wall of the L-shaped frame 7, and the pressing block 9 is slidably connected to the limiting strip 13.

[0041] In this embodiment: when the cylinder 8 pushes the pressure block 9 to move, the limiting strip 13 limits and guides the pressure block 9, ensuring that the pressure block 9 moves smoothly in the correct direction and accurately squeezes the roller 5, so that the plug 4 accurately fits with the sealing baffle 2 to seal the leak.

[0042] In a preferred embodiment, a remote monitoring and control module 14 is fixedly connected to one side of the L-shaped frame 7, and the cylinder 8 and the flow monitoring sensor 12 are both electrically connected to the remote monitoring and control module 14.

[0043] In this embodiment, staff can view the thermal pipeline flow data fed back by the flow monitoring sensor 12 in real time through the remote monitoring and control module 14 at the monitoring center. When a leak occurs, the remote monitoring and control module 14 automatically controls the cylinder 8 to plug the leak. It can also be manually operated by staff remotely to achieve intelligent remote management.

[0044] In a preferred embodiment, the block 4 is made of high-temperature resistant silicone material, which can completely fit the sealing baffle 2.

[0045] In this embodiment: when leakage needs to be plugged, the high-temperature resistant silicone plug 4, under the action of the cylinder 8, tightly fits the sealing baffle 2. Utilizing the flexibility and sealing properties of silicone, the leakage point is effectively sealed. At the same time, its high-temperature resistance allows it to maintain good sealing performance even in the high-temperature environment of the thermal pipeline.

[0046] Working principle: The inlet pipe 10 and outlet pipe 11 are connected to the external heat pipeline via flanges. The leak-sealing connector 1 is made of ceramic fiber material to ensure high temperature resistance and heat insulation performance. The flow monitoring sensor 12 detects the leakage flow and transmits the data to the remote monitoring and control module 14. The remote monitoring and control module 14 controls the operation of the cylinder 8. The cylinder 8 drives the pressure block 9 to slide outside the limit strip 13. The pressure block 9 contacts the roller 5 and pushes the roller 5. The roller 5 drives the connecting rod 3 to slide inside the waterproof sliding sleeve 15. The connecting rod 3 pushes the plug 4 to move towards the sealing baffle 2. The plug 4 is made of high temperature resistant silicone material to ensure complete contact with the sealing baffle 2. The spring 6 is compressed during the movement of the plug 4. When the plug 4 is completely in contact with the sealing baffle 2, the leak sealing is completed. The spring 6 provides rebound force after the leak sealing is completed to ensure the stability and sealing of the plug 4, realizing fast and accurate leak sealing of the heat pipeline, ensuring safe pipeline operation and efficient emergency handling of leaks.
